Sažetak
Electrical methods are commonly used in groundwater investigations but in case of deeper aquifers the electrical tomography cannot achieve deeper targets and the electrical sounding cannot ensure a complete and dense space coverage. In such a case the use of the magnetotelluric method can provide for great depths of research, as well as a good space sampling. The capabilities of the MT-method are shown in two examples of deeper groundwater investigations carried out in the north-western Croatia. In the Gotalovec area the aquifers are fractured carbonates (Triassic and Miocene) underlying thick series of Neogenic clays and marls. On the basis of all results a conclusion can be drawn that the MT-method should be applied first in similar model in order to define potential aquifers and indicate the most favourable micro-locations where reflection seismics can be applied as the latter allows for a more precise mapping of aquifer depths and faults. The second geological model, investigated in the Apatovac area, is very complex consisting of clastic and magmatite bodies. The MT-method provided for a complete and clear solution to the structural relationships in the area and gave a precise definition of the deep narrow diabase body which is mineral water aquifer.
